i'm wondering if i can store per IP bandwidth log, and then passing the data to web server.. and let the web server do the graphing.... because there's some IP host doesnt have snmp agent...

thx for advice

use RADIUS authentication to achieve this, the data is stored on the server in a very obvious form (DB), so there wouldn't be any problems to do graphs..

Otherwise you should make magle rules for each IP, SSH to the router from some Linux based machine, read the counter for each rule etc. But there will be problems with counters after router reboot and there will be no possibility to do session based graphing.
